NEW HAVEN >> If you listen closely, you can hear the end of summer sneaking up on us. The days are getting shorter, the nights are getting cooler, and there’s even a rumor that school will be starting soon.

The Yale Peabody Museum of Natural History knows it, too; that’s why it’s inviting us all to Summer’s Last Roar, a free admission day on Saturday, from 10 a.m.-4 p.m.

It’s the last time for kids and parents to enjoy a free day romping through the museum’s many wonders before the return to school.

Summer’s Last Roar isn’t just any day at the museum, however. There will be crafts, fossil carts and an instant-winner game. And maybe best of all, puppeteer Betty Blaisden will present “Roxi’s Escapade in Ancient Egypt” at 11 a.m. and noon.With free admission, you are invited to explore all the museum’s great exhibitions, including “Echoes of Egypt: Conjuring the Land of the Pharaohs,” where you will get a chance to see artifacts from this fascinating ancient civilization, including ancient paintings, hieroglyphics and a mummy. There’s even a diorama showing a mummy being unwrapped.And if you didn’t quite get your fill of cicada-watching this summer, learn all about these every-17-year-appearing insects in an exhibit that ends on Sept. 3. Find out what takes them so long to make their appearance and where they go next.

In addition to these special exhibits, there are all your longtime favorites at the Peabody as well: the Great Hall with the famous Rudolph Zallinger mural “The Age of Reptiles,” and all those real dinosaur skeletons. Visit the Hall of Native American Culture, the Discovery Room, the Birds of Connecticut and Hall of Minerals of Earth and Space.

The Peabody Museum is located at 170 Whitney Ave. There is free parking adjacent to the museum and in the Yale lots. More at peabody.yale.edu/ or 203-432-5050. By the way, from September to June, admission is free from 2-5 p.m. on Thursdays, but don’t expect all the hoopla you’ll find at Summer’s Last Roar.
